Application led October 8, 1917. Serial No. 195,447.

With the above and other objects in view,

the nature of which will more fully appear as the description proceeds, the invention consistsin the novel construction, combination 'and arrangement of parts as herein lllustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side velevation of adsan'dalf embodyin my invention; Fig. 2 1s a front end sandal in use; v

Fig. Sis a fragmentary bottom plan view of the sole of the sandal; and

Fig.4 is a fragmentary section through the sole of the sandal.

Referring to the drawings, the sole 5 is formed of two sections 6 and 7 hinged toelevation of the gether substantially at the ball part ofthe' 4 foot, 6 being the rear section and 7 the front section. formed of a iiexible member 8 running transversely of the sole and secured to the sections' 6 and 7 by means of a thread 9.

' rlhe sections are preferablyrecessed to accommodate the flexible member 8, to render the inner surface of the sole smooth for the foot. The sections are also recessed on the bottom or wearing surface, as shown at 10, so that the thread securing the flexible member 8 forming the hinge will not wear.4

To prevent sand from interfering with the relative movement'` of the sections 6 and 7, these sections are rounded at the meeting edges so 'that the distance between the sections increases toward the wearing surface, as indicated at -11. In consequence the relative movement of the sections tends to squeeze out therebetween any matter that may enter.

. tying the The hinge ,is preferably The flexible member 8 forming the hinge 1s preferably extended beyond lthe edges of the sole so that the ends 12 of said flexible -member may be lfolded about the foot resting on the'sole for the purpose of receiving a tying lace 13. For that purpose the exstrap 15 provided with a loop 16 at its free end through which thelace is threaded. In addition the rear section has side strips 17 also provided withloops 18 at the free end for engaging the` lace 13. rl`he. side strips are preferably placed in proximity to the heel portion 'so that with the rear strap the sole can be rmly secured to the rear` part of the foot. The front section 7 has at the free end thereof a front strap 19 provided with a loop 20 at itsupper end through'which the lace 18 is threaded. By means of this strap the front or extreme end of the sole is secured to the toes of the foot. It will be noted that a single' lace is used for sandal to the foot. This lace permits V ample relative sections 6 and 7 during walking.

The relatively movable sections 6 and 7 of the sole 5 permit comfortable walking over uneven ground without fatigue'to the foot, as the'relative motion is provided at a point where the foot has a natural tendencyto bend. i

While Ihave described the principle of operation, together with the device which l'.l now consider to be the best embodiment thereof, I desire to have it understood that. the device. shown is merely illustrative and that such changes may be made as are With'- in the scope of the appended claims.

I claim:

1. In a sandal, a' sole, of rigid material" formed of a front section and a rear section,

a flexible memberuniting the sections to gether, said iexible member having extensions adapted to engage a foot, straps asso,

movement between the for tying'the flexible member about the l ciated with the tWo sections for engaging a foot, and 'a lace engaging said straps and extensions for tying the same about the foot. 3. In a sandal, a sole of rigid'material formed of a fron-t section and a rear section, the meetingedges of the two sections being substantially Where the ball of the foot is adapted to bear on the sole, a flexible member uniting said sections together, said sections being recessed to receive the flexible member so as to present a flat unobstructed surface to the foot, said flexible member extending beyond the sides of the sole to fold about the foot resting on the sole, straps associa-ted with the sections, and alace e`ngaging said straps and flexible member for tying the same to the foot on the sole, the

mamas meeting edges of the sections being rounded to diverge toward the Wearing surface of the sole.

4. In a sanda1,a sole of rigid material yformed of a pair of sections, a flexible mem-v ber hinging said sections together and disposed transversely of the sole, said sections bemg recessed to rece1ve sald flexible inember, each of' said sections having a recess on the Wearing surface belowthe recess for the
